An unlicensed teenage driver unintentionally launched a 2002 Toyota Tundra pickup truck off a dead-end street and plowed into a backyard carport perhaps 1,000 feet away in San Marcos on Friday evening, a San Diego County Sheriff's sergeant said.

The driver had reached the west end of Grand Avenue and said he thought he was hitting the brakes ---- but accidentally hit the accelerator, Sgt. Mark Haynesworth said.

The truck struck a few cars on Grand, then launched down a hill and through vegetation before landing partially inside the carport of a house on the 800 block of Pointsettia Avenue, Haynesworth said.

The crash happened at 6 p.m., but the truck remained stuck three hours later, as authorities worked to pull it out of the damaged carport, he said.

The motorist, Jacob Garcia, 19, was cited for driving without a license, the sergeant said. He said investigators suspect speed played a role in the crash.
